Energy Vault’s First Grid-Scale Gravity Energy Storage System Is Near Complete 1

[cmoreride]

The facility outside Shanghai has a capacity of 100 megawatt hours (MWh); it can continuously discharge 25 megawatts for up to 4 hours.
The system is like a solid version of pumped hydro

You know this company has been charged with defrauding its investors?

Your link says "near complete" yet both your posted image and the one in the article are computer renderings.

The author's bio is embarrassing as well. Is this a bonified "climate scientist"?

@TugboatEng
So you think that photo is computer generated? Sorry to tell it's the real deal.
BTW

It also revealed that the concrete foundations have been completed for the firm’s first gravity storage project in the US, in Georgia with
Enel Green Power.

It could be but there's a whole bunch of photos on google from different angles and in different states of build. I can't find it on google maps. They are building something or other in Nevada, supposed to have started construction but no news on that.

Hmmm ...

100 MWh = 360 billion joules.

I'm going to guess that this contraption is roughly a 100 metre cube.

360 billion joules = 36 billion kg . m (ok I rounded the gravitational constant from 9.81 to 10, bite me) = 360 million kg lifted 100 metres.

360,000 tonnes. Using density 2.4 kg/m3 that's a block 100 x 100 x 15 metres of solid concrete. Or 100 x 100 x 5 metres of solid iron/steel.

Yikes.

100 MWh = 100,000 kWh. About a thousand Tesla Model S battery packs, each one weighing something less than a tonne but call it a tonne in the interest of possibly using a less-energy-dense, but more durable, battery formulation, than what the car uses.

A 10x10x10 array of Tesla Model S battery packs would be about 30 x 20 x 2 metres.

that's a block 100 x 100 x 15 metres of solid concrete. Or 100 x 100 x 5 metres of solid iron/steel.

I wonder what the CO2 footprint of the raw materials is?

It makes no commercial or practical sense. Never has, never will.
